SPOOL-RACK FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 464,623, dated December8, 1891.

Application filed March 20, 1891 Serial No. 385,795- (No model.)

To all whom it may concern:

Be it known that I, LUISE LEWY, a subject of the Emperor of Austria,residing in the city, county, and State of New York, have invented a newand Improved Spool-Rack for Sewing-Machines, of which the following is afull, clear, and exact description.

The object of the invention is to provide a new and improved spool-rackespecially designed for use on sewing-machines, and which is simple anddurable in construction, serves to-hold and look a number of spools inplace, prevents entanglin g and waste of the threads of the severalspools, guides'the thread of one of the spools to the head of thesewing-machine, and permits a ready unwinding ofthe respective threads.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter described, and then pointed out in theclaims. I

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

' ment in a closed position.

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is an end elevation of the improve- Fig. 2 is a like view ofthe same in an open position, and Fig. 3 is a reduced side elevation ofthe improvement as applied.

The improved spool-rack for sewing-machines is provided with asuitably-constructed post A, adapted to be secured at its lower end inany suitable manner on the top of the arm B of a sewing-machine, as isplainly illustrated in Fig. 3. From the upper end of the post A extendsupwardly and at one side an arm 0, and a locking-arm D is connected tothe said post A by a hinge E opposite the arm 0. A look F is held in thelower end of the arm D and serves to fasten the latter to the post A, asis plainly shown in Fig. 1, so that the upper partsof the arms 0 and Dstand parallel.

In the arm C, near its outer end, is mounted to turn a hollow shaft G,on which is secured a disk H, from which project transversely a seriesof spindles I, arranged in acircle equidistant apart. The spindles I areadapted to receive the spools J, carrying various sized and coloredthreads to be used on the sewing-Inachine.

inner end of the pin K is adapted to engage one of a series of recessesor apertures N, arranged in a circle on the disk H, the number ofrecesses corresponding with the number of spindles I on the said disk.When the pin'K engages one of the recesses N, the disk H, with thespindle I and spools J, is prevented from revolving. Then the pin K isdrawn -outwardly, the said disk and its contents are unlocked and freeto revolve with the shaft G. The outer ends of the spindles I areadapted to be engaged by the inner surface of a disk or locking-plate 0,held on a shaft P, mounted to turn in the outer end of the arm D andadapted to pass with its inner end into the hollow shaft G. When the armD is in a closed position, as is illustrated in Fig. 1, the saidlocking-plate O abuts against the outer ends of the spindles I, thuspreventing a removal of the spools J from the respective spindles I, atthe same time preventing a lateral sliding of the said spools on theirrespective spindles. lVhen the lock F is unlocked by a key or othermeans, then the arm D can be swungoutward, as is plainly illustrated inFig. 2, so that any one or all of the spools J can be removed from theirrespective spindles and new ones inserted, ifdesired.

IVhen the device is applied on the arm of a sewing-machine, asillustrated in Fig. 3, and the rack has been filled with the spools J,and the arm D has been locked to the post A, then the operator, in orderto bring the respective spool the thread of which is to be used in thesewing machine into the proper position, withdraws the pin K, so as tobe able to revolve the disk H until the desired spool is at the frontend of the rack nearest to the head of the sewing-machine. As soon asthis position is reached the operator releases the pin K, so that thespring L presses the pin K into engagement with the corresponding recessN in the disk H. The latter is then looked in place. The thread Q fromthe selected spool is now unwound from the said spool and passed to thetake-up or other mechanism on the head of the sewing-machine. It

will be seen that this thread Q can now readily unwind from the spool,turning on the horizontally-disposed spindle, the friction of the saidspool on its spindle being reduced to a minimum. As the spool isarranged horizontally, the outermost layers of the thread are notloosened until really unwound from the spool, as is so frequently thecase in spools disposed vertically, the lowermost layers then invariablyfalling to the lower part of the spool, thus entangling the thread. Aswill be plainly seen from Fig. 3, the thread Q does not come in contactor pass over any of the other spools, so that an entangling of thethread unwinding with the threads of the other spools is impossible. Itwill further be seen that when the device is in a closed position andthe key of the lock F has been removed, say, by the foreman of a shop orthe owner then the operator on the sewing-machine cannot remove' andappropriate one of the spools of the rack, as the said spools aresecurely locked in place by the plate 0 and cannot be removed. When theoperator desires to use another spool, the pin K is withdrawn, as abovedescribed,and the disk H is revolved until the respective spool is atthe front end of the device-that is, in the position occupied by thespool previously used.

Having thus fully described my invention, I

claim as new and desire to secure by Letters Patent- 1. In a device ofthe character described, the combination, with a post having a fixed armand a second arm hinged on the post and having means by which the saidarm is locked thereon, of a disk mounted to turn between the said arms,spindles extending horizontally from the said disk and adapted to carrythe spools, and a locking-plate held on the said hinged arm and adaptedto engage the outer ends of the said spindles, substantially as shownand described.

2. In a device of the character described, the combination, with a posthaving a fixed arm and a second arm hinged on the post and having meansby which the said arm is locked thereon, of disk mounted to turn betweenthe said arms, spindles extending horizon.

tally from the said disk and adapted to carry the spools, alocking-plate held on the said hinged arm and adapted to engage theouter ends of the said spindles, and means, substantially as described,for locking the said disk in place to prevent its turning, as set forth.
